Aus
der
Einen Rotor, der Lagerungsmöglichkeiten an seinem Außenumfang aufweist, wie sie z.B. durch die Lagerzapfen eines Elektroankers gebildet werden, kann man in Bezug auf diese Lagerstellen genau auswuchten. Eine aerostatische Lagerung eines derartigen Rotors wurde deshalb bisher nicht eingesetzt.a Rotor, the storage facilities on its outer circumference such as e.g. through the journals of an electric anchor can be accurately balanced with respect to these bearings. An aerostatic bearing of such a rotor therefore became not used yet.
An die Auswuchtgüte insbesondere schnell laufender kleiner Rotoren wie z.B. Elektroanker, Turbinenrotore etc. werden jedoch laufend höhere Anforderungen gestellt. Eine zusätzliche Forderung ist die Minimierung der Taktzeiten im Herstellungsprozess insbesondere für die mit dem Auswuchten von Rotoren verbundenen Arbeitsvorgänge.On the balancing quality especially fast-running small rotors such as e.g. Electric anchor, Turbine rotors, etc., however, are increasingly demanding. An additional Demand is the minimization of cycle times in the manufacturing process especially for the operations associated with the balancing of rotors.
Der Erfindung liegt die Aufgabe zugrunde, eine Unwuchtmeßeinrichtung der eingangs genannten Art zu schaffen und ein Verfahren anzugeben, mit dem die Auswuchtgüte insbesondere schnell laufender kleiner Rotore verbessert wird bei gleichzeitiger Verkürzung der zum Auswuchten benötigten Zeit.Of the Invention is based on the object, an imbalance of the type mentioned above and to provide a method, with the balancing quality especially fast-running small rotors is improved simultaneous shortening needed for balancing Time.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Lagereinrichtung zumindest zwei offene fluidversorgte Lagerschalen zur Aufnahme von Rotorumfangsabschnitten und zumindest eine einer Rotorendfläche zugeordnete fluidversorgte Lagerplatte aufweist, daß eine Einrichtung zur Erfassung des Drehverhaltens des Rotors vorgesehen ist, daß die Einrichtung zur Änderung des Drehverhaltens während des Meßvorgangs vom Rotor abgekoppelt ist und der Meßvorgang bei zeitkonstanten oder vorzugsweise bei zeitveränderlichem Drehverhalten erfolgt. Hinsichtlich des Verfahrens wird die Aufgabe durch die Merkmale des Patentanspruchs 7 und des Patentanspruchs 8 gelöst.The The object is achieved in that the bearing device at least two open fluid-supplied bearing shells for receiving rotor peripheral sections and at least one fluid-supplied one associated with a rotor end surface Bearing plate has that a Means provided for detecting the rotational behavior of the rotor is that the Means of change the rotational behavior during of the measuring process is decoupled from the rotor and the measuring process at time constant or preferably at Zeitveränderlichem Turning occurs. With regard to the method, the task is the features of claim 7 and claim 8 are solved.
Erfindungsgemäß ist bei der so gestalteten Unwuchtmeßeinrichtung vorgesehen, daß der Rotor sowohl in Achsrichtung als auch in Radialrichtung in leicht zugänglichen Fluidlagern unter Verwendung von Gas oder Luft oder eines Gas- oder Luftgemisches, also aerostatisch gelagert ist und darüberhinaus der Beschleunigungs- bzw. Verzögerungsantrieb beim Unwuchtmeßvorgang vom Rotor abgekoppelt ist, wobei der Meßvorgang bei zeitveränderlichem Drehverhalten z.B. im Auslauf oder bei zeitkonstantem Drehverhalten bestimmt wird. Die Abstützung einer Rotorstirnfläche in Achsrichtung an einer dieser zugeordneten fluidversorgten Lagerplattenfläche führt auch bei horizontal angeordneter Rotorachse zu einer sehr präzisen Lagerposition des Rotors in Achsrichtung , da strömungstechnisch eine Fixierung der Rotorlagerposition gegenüber der Lagerplatte erfolgt. Der Erfindung liegt die Erkenntnis zugrunde, daß nur durch die Kombination dieser Maßnahmen die gewünschte hochgenaue Messung innerhalb sehr kurzer Zeit erreicht wird. Mit der Erfindung wird der Rotor frei von störenden Kräften und Momenten gelagert und ausgemessen und so ein erheblich besseres Meßergebnis erzielt als auf herkömmliche Art.According to the invention is at the so-designed unbalance measuring device provided that the Rotor both in the axial direction and in the radial direction in light accessible Fluid bearings using gas or air or a gas or Air mixture, that is stored aerostatically and beyond the acceleration or deceleration drive during unbalance is decoupled from the rotor, the measuring process with time-varying rotational behavior e.g. in the outlet or at constant time rotational behavior is determined. The support a rotor end face in the axial direction of one of these associated fluid-powered bearing plate surface also leads with horizontally arranged rotor axis to a very precise storage position of the rotor in the axial direction, as fluidically a fixation of the Rotor bearing position opposite the bearing plate takes place. The invention is based on the finding that only by the combination of these measures the desired highly accurate measurement is achieved within a very short time. With the invention, the rotor is stored free of disturbing forces and moments and measured and thus achieved a much better measurement result than conventional Art.

Eine weitere Ausgestaltung der Erfindung sieht vor, daß die Lagerschalen austauschbar an Lagereinrichtungen angeordnet sind und die Lagereinrichtung ein Fluidversorgungssystem hat, das einen fluiddichten Anschluß von insbesondere unterschiedliche Fluidkanäle aufweisenden auszutauschenden Lagerschalen ermöglicht, wodurch eine vorteilhafte Standardisierung der Lagereinrichtung bzw. eine Modulbauweise der Unwuchtmeßeinrichtung gegeben ist. Dies gilt auch für einen Vorschlag, nach welchem vorgesehen ist, daß die Lagerplatte austauschbar an der Lagereinrichtung oder einem nicht schwingfähigen Bauteil der Unwuchtmeßeinrichtung angeordnet ist und die Lagereinrichtung oder das Bauteil ein Fluidversorgungssystem hat, das einen fluiddichten Anschluß von insbesondere unterschiedliche Fluidkanäle aufweisenden auszutauschenden Lagerplatten ermöglicht. Es kann vorteilhaft ein gemeinsames Fluidversorgungssystem zur Fluidversorgung sowohl der Lagerschalen als auch der Lagerplatte eingesetzt werden. Die Lagerplatte kann an einem Teil der Unwuchtmeßeinrichtung, der unwuchtinduzierte Schwingungen durchführt, wie Lagerständer oder Lagerbrücke, oder einem Bauteil angeordnet sein, das keinen unwuchtinduzierten Schwingungen unterworfen ist, wie z.B. der Rahmen.A further embodiment of the invention provides that the bearing shells are arranged interchangeably on storage facilities and the storage device has a fluid supply system, which allows a fluid-tight connection of particular different fluid channels exchanged bearing shells, whereby an advantageous standardization of the bearing device or a modular design of the imbalance is given , This also applies to a proposal according to which it is provided that the bearing plate is arranged interchangeably on the bearing device or a non-oscillatory component of the unbalance measuring and the bearing means or the component has a fluid supply system, which allows a fluid-tight connection of particular different fluid channels exchanged bearing plates , It may be advantageous to use a common fluid supply system for supplying fluid to both the bearing shells and the bearing plate. The bearing plate can on a part of Un balance measuring device that performs unbalance-induced vibrations, such as bearing stand or bearing bridge, or be arranged a component that is not subject to unbalance induced vibrations, such as the frame.
Eine Einlagerung des Rotors in einer definierten Lage wird wesentlich erleichtert durch die Anordnung von zwei Lagerplatten, zwischen denen der Rotor mit seinen Stirnflächen angeordnet wird. Die genaue Fixierung der Lage des Rotors in Achsrichtung erfolgt strömungstechnisch über das an der Lagerfläche einer Lagerplatte in den Zwischenraum zwischen Lagerplatte und Stirnfläche ausströmende Fluid.A Storage of the rotor in a defined position becomes essential facilitated by the arrangement of two bearing plates, between where the rotor is arranged with its end faces. The exact Fixing the position of the rotor in the axial direction is fluidically via the at the storage area a bearing plate in the space between the bearing plate and the end face fluid flowing out.
Vorteilhaft ist auch die Ausbildung der Einrichtung zur Änderung des Drehverhaltens als Riemenantrieb, dessen Riemen an zwei sich im wesentlichen gegenüberliegenden Rotorstellen anlegbar ist, da hierdurch während der Beschleunigung bzw. des Abbremsens des Rotors nur kleine Querkräfte auf den Rotor wirken, die die aerostatische Lagerung kaum beeinträchtigen können.Advantageous is also the training of the device to change the rotational behavior as a belt drive, the belt on two substantially opposite Rotor points can be applied, since thereby during acceleration or the braking of the rotor only small lateral forces act on the rotor, the can hardly affect the aerostatic storage.
Der Vorschlag, den Riemenantrieb mit einem V-förmig ausgebildeten Bereich mit veränderbarem Öffnungswinkel zu versehen, in dessen Inneren der Rotor angeordnet ist, hat Vorteile hinsichtlich des Bauraums und in Hinblick auf die Betätigung zum Anlegen bzw. Wegschwenken des Riemens vom Rotor. Hierzu können einfache fluidbetätigte oder elektrisch betätigte Stelleinrichtungen eingesetzt werden, deren Stellbewegung darüberhinaus einfach automatisiert werden kann.Of the Proposal, the belt drive with a V-shaped area with changeable opening angle to provide, inside which the rotor is arranged, has advantages in terms of space and in terms of the operation for Applying or swinging away the belt from the rotor. This can be simple fluid actuated or electrically operated Actuators are used whose adjusting movement beyond can be easily automated.
